One of China’s most famous actors, Fan Bingbing, has been ranked last in a list of celebrities for their social responsibility, raising further questions about her sudden disappearance.

The 2017-18 China Film and Television Star Social Responsibility Report ranks Chinese celebrities according to three criteria: professional work, charitable actions and personal integrity, state media reported.

A list of the rankings from the report published by state media outlet China Daily showed Bingbing received a score of 0 per cent.

According to the ranking list, only nine celebrities received a passing score of 60 per cent — including Bingbing’s fiance, actor Li Chen.

The report was authored by the China Social Responsibility 100 Forum, which is said to have been established by experts, entrepreneurs and social activists.

Bingbing, who is best known in the West for her roles in the X-Men movie franchise, has not been seen in public since July 1, sparking rumours she is in prison.

She was publicly linked to a tax evasion investigation in May, and has since gone silent.

Last week, a state media report from China’s state-run Securities Daily said that Bingbing, 36, was “placed under control”.

But the online story vanished not long after it first appeared, leading to much speculation on social media.

Top ranking naver articles are about Fan Bingbing, allegedly her contract/tax evasion is only the tip of the iceberg, she is also accused of bank lending (offering illegal loans) & corruption and will face a criminal trial. Another media reported she's been in jail since August. pic.twitter.com/1ZcMMAh8VE
